arch/x86/Kconfig: Add deprecation warnings for LATE_CBMEM_INIT
The deprecation of late (post-romstage) CBMEM initialization was announced in this blog post: https://blogs.coreboot.org/blog/2017/05/08/announcing-coreboot-4-6/ There are two warnings: * In LATE_CBMEM_INIT's help text, I've added a multi-line warning, that aims to explain the problem. * In src/mainboard/Kconfig (just below the mainboard selection), there's a warning which points the user at LATE_CBMEM_INIT, if such a board is selected. Also update the function that needs to be implemented, as pointed out by Keith Hui and Kyösti Mälkki.
